This one is quite a physical workout. Lots of “Clark-like” slurring in the mid to upper register. It helps me to think of creating a really good foundation of air – “bedrock” – and focus on using my embouchure and aperture to manipulate the pitches. You may be tempted to arch the tongue and “hiss” the high parts out like you would if this were a lead trumpet part. Unfortunately, I don’t think that approach gets the desired effect of a relaxed smooth sound in all registers.
